On the evening of the 3rd of November in 1791, a coalition of Ojibwe, Ottawa, Potawatomi, Mohawk, Oneida, Onondaga, Cayuga, Seneca, Tuscarora, Wyandot, Wabash, Cahokia, Kaskaskia, Michigamea, Peoria, Tamaroa, Mississaugas, Menominee, Shawnee, Lenape, Miami, Kickapoo, Chickamauga, and Muscogee tribes amassed an army of around 1,100 fighters, in the forests near present-day Fort Recovery, Ohio. The army was led by Little Turtle of the Miami, Blue Jacket of the Shawnee, and Buckongahelas of the Lenape. It also included a large number of Potawatomi fighters. Opposing them was the first American army ever assembled following the American Revolution. Historians today remember the battle by the name of St. Clair’s defeat and the Battle of Wabash River. It led to the first ever Congressional investigation of the executive branch, and today remains the most decisive loss in the history of the American military, with the Americans suffering a casualty rate of nearly 97%.

That's amazing, especially since the traditional territories of some of those First Nation groups were from fairly far away in Canada. They must have traveled a long way by foot to participate in the battle.
